Trash isn't full of valuable materials though. It's full of food (mostly water by weight I guess) and paper and plastic with a little bit of other stuff mixed in.
True, I was being hyperbolic (oof, the pun material is just too good). But the organics pretty much take of themselves, leaving behind just the bits we might want to reuse. Of course, we could be composting the organics and reusing them now, my city does that, though they give the compost away to any takers, which suggests the economics are still a work in progress.
Right, I understood you were exaggerating and replied because the energy investment will probably never make sense if the goal is material recovery (a landfill is the worst ore for anything interesting).
It might happen for other reasons like remediation or whatever.
